Why do we care about ergonomics?
1. Helps you be more productive
2. Helps reduce workplace injuries
Four Main Areas
There are four main areas that people who use computers should focus on:
1. The Monitor
2. The Mouse & Keyboard
3. The Chair
4. The Lighting
The Monitor• Place the monitor as far as your eyesight will allow – a
minimum of 20 inches is preferred• Place the center of the screen at a 15 degree down angle
from your eyes• Bend your neck slightly while keeping your head
perpendicular to the floor• Line up the monitor with the keyboard
Lighting • Your work area should be moderately bright• Do not use ‘task lighting’• Mix incandescent and fluorescent lights to reduce flicker
and provide good light color
The Keyboard• Position the keyboard slightly below the elbows to let your
wrists remain straight• Keep your hands and arms off any supports while typing• Do not use the feet on your keyboard – the flat (negative)
angle keeps your wrists in the proper position
The Mouse• Place the mouse at the same level and immediately next
to the keyboard• Use your elbow, not your wrist or shoulder, to reach your
mouse• Don’t rest your wrist on anything while using the mouse
Chair Setup & Posture• Use arm rests• Adjust the height of the chair so your feet can rest
completely on the floor• Allow 1-3 inches between the edge of your seat and the
back of your knees• Don’t cross your ankles• Hold your head perpendicular to the floor• Let your upper arms hang naturally from
your shoulders• Keep your lower arms parallel to the floor• Keep your wrists straight• Stretch!
